Sodium-Ion Battery State of Charge Estimation Accuracy
As a battery engineer who has spent the last decade building lithium and sodium packs for industrial customers, I keep hearing the same concern from system…
Sodium-Ion Battery Formation and First-Cycle Efficiency
Formation is the first controlled charge and discharge a sodium-ion cell receives after assembly. I have run formation lines for both lithium-ion and sodiu…
Sodium-Ion Battery Cell Qualification Under IEC 62619
When a buyer asks whether a sodium-ion cell is “qualified”, the word hides more than it reveals. At Horizon Power we see datasheets that quote 4,000 cycles…
Sodium-Ion Battery Dynamic Voltage Support and Ride-Through
Grid operators care about voltage as much as energy. A feeder that sags when a large motor starts, or rises when midday solar floods a rural line, needs r…
Pre-Shipment Acceptance Criteria for Sodium Ion Packs
Twelve years in lithium battery development taught me that the pack you ship is not the pack you tested on the bench. The gap between a working prototype a…
Sodium-Ion Production Line Compatibility with LFP Lines
I have spent the last four years qualification testing a sodium-ion battery on equipment that was originally purchased to make lithium iron phosphate packs…
Sodium-Ion Battery Charging: Charge Limits and SOC Window
Why Sodium Chemistry Needs Its Own Charg Limits
Twelve years of my career went on lithium iron phosphate packs for forklifts and stationary racks. In the l…
Sodium-Ion Battery for Mobile Signage and Event Trailers
Standing beside a signage trailer at 5:40 in the morning, in November, on a wet fairground, gives you an honest view of what mobile power really means. The…
Sodium-Ion Battery for Food Trucks and Mobile Kitchens
In most of my years designing battery packs for vehicles, the hardest brief has never been the biggest one. It is the awkward one: a pack that has to run a…
Sodium-Ion Battery for EV Charging Station Buffer
Demand charges have quietly become the largest operating expense at many public charging sites, and I have watched this pattern repeat across every plaza w…
